在农业生产中，耕深的稳定性是评价耕作质量的重要指标。为此，结合目前微耕机耕深不稳定的现状，设计了一种耕深辅助控制系统，主要用于辅助控制微耕机的耕作深度，提高微耕机的耕作质量。该系统主要由耕深检测装置、控制装置、执行装置和显示界面组成。检测装置用来间接检测耕深，控制单元对检测到的信号进行分析后控制电机转动，从而间接控制耕深调节阻力杆的上下移动，以实现耕深辅助调节。显示模块用于显示实时耕深，为操作人员提供参考。田间试验结果表明：耕深稳定在120～130 mm 时的耕深稳定性变异系数为5．82％，满足农艺要求。所提出的耕深测量方法、辅助控制执行装置和显示界面对微耕机设计具有一定的参考意义。

Stability of tillage depth is important to agricultural tillage .Combining the current situation that tillage depth of the micro-farming machine is enormously unstable , presents an automatic depth control system applied in the micro-farming machine .The main objective of the system is to stabilize tillage depth of the micro-farming machine .The system has four parts: the detector , the controller , the executor and the display interface .The detector is used to detect tillage depth indirectly .Then the controller controls rotation of the step motor , regulating the depth of resistance rod into the soil for controlling running speed of the micro-farming machine , until tillage depth achieves the desired depth .Moreover , the display interface shows real-time tillage depth to provide the running condition of the system for the operator .The field tests showed that the system improved the stability of tillage depth because when cultivated tillage depth range is 120~130mm, variability coefficient of depth stability is 5.82%, meeting the agronomic requirement .That could prove the sig-nificance of the system in future micro-farming machine design .
